PH issue or pest/disease or nutrient deficiency?
NY_Gashousestarted grow question 2 years ago
Opened the tent up yesterday and noticed some burning and unusual spots on a few leaves. Plant is 3 weeks old today, I water with nutrients every other day and plain PH water on days I do not water with nutrients. Growing in coco coir, I aim for 6.5 ph water

Grannie doesn't know where she talks about.
Your problem is that coco is a hydrophonic medium and for that you need to water the plants with pH 5.8
I would give them pH 5.5 the first time and give double the water that you did before to make the medium more acid.
Afther that just give the same amount as you did before already and give pH 5.8
Happy Growing! 😋

Your pH should be lower in coco I ph at at 5.9 until later in the grow during flower then I ph to 6.2 no higher

There's a lot more information we need in order to try to help you with this.. to ME it looks like there are a couple of things going on - heat stress (leaves curling) and the beginnings of a calcium deficiency - but we need a diary to really tell us what's going on... so go start one and come back to ask your question again please!
Good luck

Discolouration on fan leavesGetting a white discolouration on my fan leaves. Thought it was residue from watering with nutrients as sometimes water will land on the leaves. But it doesn’t rub off, some parts look like it’s scratched into the leaf, some parts look almost bleached. But also considering PM?

Spotty/Blotchy Discoloration on leaf.What is this spotty/blotchy discoloration on this leaf? None of the other plants have it, it didn't brush off when rubbed. Hoping it isn't a mold or a pest...I have been keeping the humidity around 65% with good airflow, but I'm wondering if it's time to bring it down to 60%.

Still K deficiency?I fed some flower fuel to plant 1, half strength, and the discoloration got worse! Some leaves almost look like cal deficiency so I also sprayed foliar with calmag, just now when I got home. Is this still looking like a K deficiency? If so, should I feed it again or wait?

Nutrient DeficiencyIs this a PH issue showing or nutrient deficiencies (possibly caused by bad PH anyway, at 6.2 atm higher from earlier in week.)? Possibly magnesium deficiency, looking at pics. Anyone confident? Been hot in tents as well but water temps kept decent about 68-70.

Suggestions as to why this plant is a mess!First grow - Blueberry Auto outdoor. Pathetic thing is on day 36 from direct sow. White splotches since week 2. Subjected to excessive heat, an oversized garden bed, lack of sunlight and overcompensating with supplemental grow lights. CoM organic nute/soil. Any solid diagnoses?

Nutrient lock out?Well watered my plants with great value drinking water. Ph 4.11. Didn't check ph until week 3. Currently upping it to 6.5 after I found the issue. Does this look like nutrient lock out? They were in root Riot starter plugs. And I fed the some clonex and great white microbs.
