I think you're pH is too low... From what I've seen, a pH of 6.2-6.8 is the ideal range for nutrient uptake. From the one picture its hard to say that's the only problem though. Looks like you may have a humidity issue as well.

whats the temp and RH in the tent? Also whats the DLI or PPFD for the canopy? Looks like its to dry and or to hot, could be getting compounded by the lights. I also have a feeling something could be off in the roots like oxygenation or some weird shit growing. Smell and feel the roots, are they off putting in any way?? Good Luck!

What happens if fan leaves all fall off before maturity?This is first time ive dabbled with ilgm autos. Plants grew twice the recommended size and are on the 9th week. The pistols are 90% white and the fan leaves are yellowing fast. I've never experienced this and am afraid the yellowing will affect buds before ripe. Suggestions?

Early senescence on Runtz?Based on your experience growing Runtz and/or the pictures posted below, what week would you say we're in? I'm asking cause leaves are yellowing and unless I overwatered them it looks like a very early senescence, no? I'm a newbie so there are obvious things I don't see :) Cheers

Hi 8th week of flower. Bottom leaves have turned yellow and died and yellowing is rapidly moving upwards. I think it's nitrogen deficiency so I've added more Biobizz Grow. Would be good to get an expert opinion! Thanks

Does the paleness concern you?Plant #1 seems a bit more on the pale green/yellowing side of the spectrum. Especially compared to plant #2. I have been feeding this week on a gradually increasing schedule. Not enough characters to go into it here.

Nutrient lockout?Having a problem with bottom leaves turning yellow and dying. Starts off with brown on edges and tip, then leaf yellows and dries up. Potassium deficiency? PH problem? I flushed plants yesterday with 6.5 ph water and sledgehammer flush from fox farm. Pictures on week 10. Thanks!

Nutrient lockout? [first grow]My plant’s started showing signs of nutrient burn, so I have flushed them with just water, after 1 day they turned to worse condition than before. Is it nutrient lockout? Or just deficient? Appreciate every feedback!

Yellow leaves working out towards tips Yellowing of lower leaves, from the stem working towards the tips. It’s been hot and they’ve been home alone for 5 days with just one water on the 3rd day. They had a small amount of bloom just before I left! During veg they were on fish mix, but not very much (1/2 dose).
