Serious Problems, cause unknown.

[skylined]

Several of my plants leaves are dried to point of crunchiness, curling upward, and yet are not browning starting at the tips. The leaves just seem to go dry and yet retain some of the green color, some is brown. Hard to describe but this problem is INCREDIBLY frustrating and it does not look like nutrient burn. I am completely at a loss as to the cause of this. Any help is appreciated. I can't post a picture because I have no camera. I'm using pro-mix soil, no adulterants. I measured water pH at 6.5.

Thanks in advance.

Peace,

With no pics its hard but I'd say if you're sure you have a good PH then its over fert. The curling and dryin sounds like nute burn although you may see no burn but just leaves dryin up and dying. How old are the plants? Can they handle a hearty flush of PH balanced light nute solution? Thats the best bet. A few days later fert them with a proper dose. Lots of flushing for each.

I did give them a good dose of ferts, and Hashberry is a light feeder....that might do it. How much water should I use to flush out a two gallon pot? Thanks for the rsponse.

Hi SKYLINE...

I would not feed them for awhile... like at least 3 waterings.... each water should be a serious flush... I would use 2 gallons of water... each time.

I would also make the first flush at 5.8 and the second flush at 6.3 and the third flush at 6.8...

I would also transplant into a different container and different soil.. and mix in at least 20% perlite...

cheers

J.C. says in the grow bibles to flush with three times as much water as is the volume of the container. i.e. two gallons X three + six gallons of H20. Flushing stresses the plants rather much, but it seems this may be a variable solution to your frying; particularly since you fertilized upon a rather "buffed up" soil.

Important would be to mention how old your plants are......

Don't forget to keep the bulbs at a good distance; min- 1ft for 400w and +/- 1.5 ft for 600W, in this case I would lift the lights at least a little bit so as to lessen the heat stress to the leaves after you flush. Do this after you flush, but return them back to the proper position soon to avoid a stretch- use upon discretion.

G' luck

Easy, with flushing and transplanting. The less stress the better.. Pick one- or perform them at least awhile apart, it's always important to give the ladies time to adjust to the prior action . I think the age of these ladies is a crucial factor....

The 3times volume rule is good and the lower PH of 6ish is good too. Dont get too crazy with minutia but yes........FLUSH(3 times volume of pot, Low PPM nute if at all, PH slightly acidic) This will not hurt the ladies 1 bit. Do not TP right after if at all. After the soil begins to dry then fert(prob 4 days later).

A good thing is to test the water runoff right when it starts and at the end of each flush. The 1st reading I bet will be high if not nuclear. The final reading should be low and the PH should be somewhat close to the required range.

Keep us posted as this is not a big issue and above should rectify np. I had the exact same issues when a buddy did my fert on my last crop. I did not flush cuz I caught it early. I just heavily watered for 3 waterings with just water+hygrozyme(natural PH down for me) and they sorted out within a week and all dryness and crumbling/curling of leaves were done. My AK was higt harder telling me it was a fert issue. My AK is a lighter feeder than my other stains. If the burning isn't dad then water ph balanced could help but I'd still say flush for peaco O mind.

Give us some more info too like age strain so we can help more.

I measured water pH at 6.5.

Ph in promix should be 5.6 to 6.2 You should try feeding weakly with every watering adjusted to about 5.8 to 6. Dolomite lime will eventually run out in the promix so you should reapply only if the ph is low or add cal mag to your water.

One of the plants in trouble is Hashberry. They are about 15 inches tall, probably about six weeks old. I watered them with the solution of 5 ml of biobloom, 1 ml floralicious plus, 1ml of super nova, 1ml of dark energy. Clearly this was FAR too much for Hashberry, especially this particular pheno. I have many clones of the plant, so I'm not too worried that I'll lose it but its irritating because this particular plant is in flower and I'm sick of f ucking everything up when I hit the flowering stage. I have this pH test kit with pH up and pH down, how much should I add to a gallon of water to stabilise it at around 6 (I tested the water, after several days evap for dechlorination, at 6.5). I add a significant amount of perlite to my pro-mix BX, nothing else.

Peace,

For all your troubles throughout the growing process. A good flush could never hurt. If that doesn't free up the roots to take up nutes, then I would use this guide to figure out the problem. Without a camera, you are the only one who can really see them. Hope it helps! Good luck!
