10) No adjustment of water PH because it is 7.
11) Using BioBizz BioBloom, 0.5ml per litre. Plants get 500ml every 4 days. Only been using nutes since day 28, this is day 33.
12) No special additives or teas.
13) Are your ph levels stable, or do they fluctuate?
14) Ingoing water PH is 7.
15) I do not foliar feed.

Growroom:
16) Indoors.
17) Homemade growbox, 2x2 feet floor and ceiling, 3ft high walls, made of untreated chipboard.
18) Lights on temp/humidity is 28 celsius (82 farenheit)/35%, for lights off it's 19 celsius (66 farenheit)/50%.
19) No insects in the growbox.

Strain:
20) Growing Lowryder #2.

Problem:

I have already started a thread about my plants and Weezard was helping me, but i didn't fill out a sick plant report and i think that's why only one person was helping.

I hope it's OK to fill out the form and start a new thread, as there is a new problem anyway !

Here are pictures of plant A :

I'm worried about the twisty leaves on that one, from what i've read magnesium deficiency seems to fit, but i know nothing !

Pictures of plant B in next post.

Attachment 284277

Both plants were overwatered a couple of weeks ago and plant B was repotted because she was the worst affected.

I'm worried about the twisting of the leaves on plant A and would just like a general opinion on plant B as to how she's recovering from the watering.

Thank you for reading :)

This is a link to the thread where i didn't fill out the form and so didn't get many people's attention, but Weezard was very helpful :

Thanks again,

nibs.

from what ive been reading, yes it seems to point to magnesium. the grow bible says to add 1/4 to a 3rd tablespoon of epsom salt to 3 gallons of water and water ur plants, but dont over water. ide add a little of that water at first and check for signs of improvement

Thanks Matt. I've just done a PH test of the water after nutrients are added and it's looking like adding nutes changes it from 7 to 7.5.


Thanks,

nibs.
