several problems with my plants..

[O.G.Monk]

Hello everyone,

i am growing 2 cream caramels from sweet seeds and 2 blueberrys from vision seeds 2nd grow.. they are at day 55 and they look small for 55 days of growing but i am not sure i hope you tell me..

I probably must dealing with nitrogen def from first week.. i started with 155 t5 lighting for one week with seedlings mix soil the light close to the plants and everything was perfect, but after some days i saw the first true leaves yellowing and falling and then the next set of older leaves.. so i started watering with nutrients biobizz series.. also before i start feeding i saw some kind of strange holes at some leaves but it is not from bugs, its like the plant is growing strange..

i transplanted to all mix soil by biobizz at 2nd week and feeding them with the recomended dosage of biobizz..

now they are under 600w hps growlight the temps are normal 20-26 c max humidity gets low sometimes..

i want to mention that my previous grow(firstgrow) was with the same soil that i am using now i had some autos that didnt grow well they was realy stunned and they started flowering at day 15 so i start over with non autos.. and before that i had the soil and the nutrients in a werehouse for about a year but i dont think they are expired or something like that because they still smell the same like the first day i got them..

but i dont know maybe this is the root of the problems..

here is the pics i hope someone can help me out..

peace..

How close is the 600w to the canopy? When you switch to HPS when they young it needs to be far away. It looks like a bit of bleaching from the light and also they look underfed, but could be pH. Make sure that light is really high for now to take that out the equation, most the time that is the cause. I see you have fans in there so gather air circulation and that is ok. Wait for a soil grower for feed/ph issue though, I only grow in coco so cant advise

i switched at day 25 to hps..

the distance is about 50cm far away from the canopy

so when they are young the light must be far away? i didnt knew that and i had it close because i thought the plant grow stronger that way without stretching..

btw thanks for your advices

i also see some pink stems at some plants..

I would have a 600w triple that distance for 25 day old, you drop it lower as they mature and flower. I find the best lighting to stop stretch to be a 250w CFL veg light, or a metal halide with a spectrum designed for plants. They always stretch more to a red biased HPS, searching for the blue. I actually use dual spec HPS now, which rock by the way

Those newer pictures do look like some lockouts occuring, but that could be pH as much as the medium. Do you know the pH of the feed you are using?

when i was feeding the ph was 6,3 and the days i was not feeding the ph was 5,5-5,8

Hi O.G.Monk

I don't see light bleaches but they surely seem underfert... Which is strange because that shouldn't happen with biobizz allmix at this point, especially if you had some more ferts. Your pH shouldn't be an issue neither considering the buffer effect of the soil, but maybe there's something wrong with the roots system maybe caused by overwatering ? How much do you water those (frequency and quantity wise ?). Also what's the night temperature ?

well i water every 3-5 days one litter per plant

night temps must be around 16-17 celsius

Root bound perhaps? Extremely compact growth that's for sure. The lower yellowing leaves look as if the roots have run out of room. If you want them to grow taller try get a longer pot. Good luck

i took off the pot and i dont see roots yet should i tranplant it tho?

Those look like my first attempt with one gallon fabric pots.
I water every other day, small fabric pots dry out too fast and require more frequent watering. When your dirt gets too dry all sorts of deficiencies pop up.
Same genetics in same size plastic pots were all fine sitting right next to the plants I had looking just like yours in fabric pots. I reported in plastic and problems faded away.
I went back to plastic pots for vegging and haven't had any issues since.

the true is that third day soil is dry like the sand

this must be it they need more water..

i dont have plastic pots but i will water every second day

do you know if i switch to 12/12 at that size of plants what yield should i expect ?

or its better to grow them a bit bigger and wait longer?

Nah don't replant it if they look like there is still room for them to grow. Try moving that light of yours up to encourage that stretch. Plants stretch about a foot two two feet during bud, try to invision your plants that high, would they do better with the space in between them?

how many days are you waiting betwen waterings with plastic pots..?

i transplant them to 25 lt smartpots and after i did it i saw your post i will try to remove them and put them in the old or 1 liter bigger pot..

i dont understand its 2 months and i dont see the roots at the 3 liter pots..

i am very disappointed i dont know if its worth it to try save them and grow them big or throw them away and start over with other seeds..

i cut all the yellow and dead leaves of the plants and now after 2 days next sets of older leaves are yellow again and i water every time with nuts in the all mix.. i dont know what is wrong

Sounds like they're not liking something in your soil. Or you could have over or underwatered at one point and damaged the root system. I would want to get a look at the roots. If you can't see them and it's been 2 months something is very wrong. I'd gently try to dig down to the rootball and see what's going on with them. And get some new dirt. Some leaves are showing signs of a ph issue. Could just be the old soil, not familiar with that brand. Your humidity also you should fix. If humidity is low it can mess with transpiration.

so you are telling me to dig the soil take out the plant from the roots without damaging the plant and transplant it to other soil?

it sounds realy out of my skills to achieve this without damaging the plants..

i just bought plastic pots one liter bigger than the last pots i had they was some kind like smart pots, i transplant them to final pots today morning 25lt without water because lights was just off.. i will transplant them to the plastic ones and water them with phed water and a litle bit superthrive and i hope that helps, to be honest i am afraid to try dig to the roots any other advice on that project?

thanks by the way
