answered grow question 6y ago
Calcium. Not enough. pH is probably low that can't uptake enough. Can raise your pH or add cal to your next feeding

Interveinal chlorosis and dead spots on leaves, deficiency?
This started appearing about a week ago, after I watered until runoff with plain water. It's on a couple of leaves higher up both plants and seems to be progressing. I am feeding advanced nutrients Grow Micro and Bloom but have been using very low doses, like 1ml/L.

Strange discoloration
The plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

My OG's are starting to yellow much earlier than I am used to. Pictures are taken on day 35 and they're supposed to be around 8 weeks of flower. Could the yellowing be due to high pH in the medium or maybe disease or am I just being paranoid?

Slow growth yellow leaf edges what to do?
Plant growing slowly (but still growing) with weak growth tips and yellow edges on leaves with interveinal chlorosis. Looks like overwatering / magnesium deficiency to me. I use a weighing scale to know when to water, but started the plant in 25L pot so this might have caused it.

Crispy Yellow Leaves
Inflow EC=1333 w/ PH=5.8 vs Runoff EC=658 w/ PH=6.0. Insufficient nutes due to light intensity? Perhaps my PH meter is inaccurate? Light is 42 inches from canopy or ~600 PPFD. RH 65%, Temp 80 F.

Interveinal chlorosis on older and new leaves. Magnesium deficiency?
I've been maintaining my nutrient mix pH at 6.2-6.3 as recommended by Biobizz. However Ive been noticing magnesium deficiency like symptoms on the older and newer leaves. Should I increase my pH to 6.5-6.7 or is this something else entirely?

Roots getting brown
My Ph probe didn't work, PH was at least more than 0.30 (maybe 0.60) than displayed. As a result they had multiple chlorosis, now septoria leaf spots and possible Pythium since the roots are getting brown. What would you do to save the crop ? Adding mycorrhizae? Thx!
