I got a couple of questions for someone more experienced

[ganja4]

Hi to everyone...
I have been growing a critical kush, a ww, an og kush and a northern lights since 5th of november when they sprouted.
ogkush had been topped 2 weeks ago
critical had been fimmed 2 weeks ago and lsted
This is the info of my grow

tent is 120x60 3feet x 2 feet
I grow in 4 x 16 litres(4 gallons) buckets dwc
Light is roleadro 300w at 55cm or 21in height
ph from 5.7 to 6.2
res temps 18c or 64f
lights on temps around 21c-22c or 70f-72f
lights off temps around 19c or 66f
humidity 40% at most
i use flora trio .Schedule is from their nutrient calculator
i also use superthrive,bioroots and voodoo juice at 60% of their suggested dosage
Now the ppm
they all run around a total 1200-1300 ppm with my tap water being 215 ppm
the critical kush is at 1340 .The ww is at 1390 .The Northern Lights is at 1345 and the ogkush is at 1323.


1.Northern lights and ww are very small for being 5 weeks old.

2.Critical and especially og ....they are TOO bushy .I mean look at the og..The fan leaves are getting huge and the new growth keeps coming more and more .I searched and all i found is how to make your internodes grow closer to eachother.I know its weird but .... how can someone scrog with this ?? The new growth is not getting any taller.Today i moved the light at 60cm (23.5 in).But from what i read so far from others using the same light, at this height it is not too close. I also know about how the difference between day and night temps affect the internode spacing.Unfortunately the tent is in my bedroom and i cant get it any colder when lights are out .And i tried to raise the temp during lights on but my res temps are rising also. .....I even read about how touching your plants makes them grow shorter internodes cuz of a hormone they produce due to touch.In anyway. Any opinions of that would be usefull.Is that extreme ?Will i have a problem cuz the plant grows like that ? Or is it sth good ?Will i be able to scrog that >?

3.Critical has these brown spots on the edge on fan leave.As i said it is at 1340 ppm.I know about watching the difference in measurings to see how the plant is consuming more nutes or water.I got to 1340 by increasing slowly.Do u think i reached the limit and this is a nute burn ? But the other 3 plants are way smaller and they dont show similar signs.Plus the critical was using more nutes than the other 3 from dayz before.
Yesterday i changed the res on the critical.But i think its getting worse.
Thats all .
Any help will help me learn
So the first is the critical and the second is the og
Thx

Those ppms seem really high. I only have gotten that high when at the peak of flower with some nutrient hog plants. Most plants I find are happy at 900-1000ppm max.

Everything else looks really good. I would cut out the voodoo juice by now. And the superthrive.

Your plant showing Mg deficience,soon she will show more N problems cause of uptake,problem could also be in Ph and then starts problem for plant to absorb nutes..

First of all thx for reply.
Is it possible that this high ppm slows their growth rate ?Or the burn would be the first symptom in any case . I am asking this cuz the other three plants (which are smaller in size and root mass )dont show any sign of burning. They r just not growing as they should

 

[Athos]

First I would lower the solution ppm way back. See those really dark green fan leaves? That's Nitrogen toxicity. The burned edges could be the same issue.
I would use a nutrient solution of 400 to 500 PPM total, that's including your tap water. In flower you can slowly rise it to 800 pmm total.

As for the slow growth. Don't lower the lights off temperature, on the other hand, your lights on temperatures are kind of low, try to keep it above 23°C, at 24°C to 26°C is ideal. Low temperatures can slow growth to a crawl.

Also, topping do promote short bushy plants and it can take 2 weeks for them to recover from the shock of it.

 

[ganja4]

I will.I must find the sweetspot so my res temps dont get high also . Maybe mylar around my black buckets .
Thx anyway bro

 

[Athos]

I've seen people using ice coolers for DWC, you might want to check that.
Some great results keeping the water temperatures in check

 

[ganja4]

I am tryin to avoid that .I have done it and at some point its a pain in the ass . I will however use it as a final solution.I rly hope i can manage with some reflective material round my buckets.Its not a huge temp problem afterall...
thx mate
