Crispy Yellow Leaves
MediciGrade
started grow question 6y ago
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.

everyone says 5.5-6.0, but unless your fertilizer says so, you should more likely stick to 6-6.5.

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!

Mag Def?
Does the yellowing between the veins on these lower leaves look like a magnesium deficiency?

PH Fluctuations and/or Nutrient Issues?
I'm Running a Recirculating Deep Water Culture System( hydro). Had PH dropping dramatically a few days back but did a full water change and everything has stabilized. Just Flipped to a 12/12. Does it look like that was the issue or is it nutrient toxicity/deficiency. Or Stress?

First grow yellowing seedlings :( nute problem?
I seem to be following all the instructions on grow temperature range, light distance, and watering schedule(only watering hen the medium is drying); I've hardly used any nutes until day 22 as advised and I personally think this has caused me some issues although I may be wrong.

First week and never had little plants struggling so much to grow. Please, read my comment about the first week to a detailed explanation of the problem. The question is, what else can I do, except from waiting? I don't want to over do (again)

Top Leaves are becoming yellow from the inside out.
Hi, anybody know what the problem is with this plant? The top leaves are becoming yellow/white from the inside out. Also the leaves have a different shape. The plant is in open soil and I give her water and sometimes some veg nutrients. Thanks in advance. (Last picture)

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.
