It could be cal mag over because she need in veg most of it so may decrease cal mag for few weeks and also may need pk anyway I had similar problems last time I couldn’t fix but the buds was nice try also to increase to 40-50 % umidity and 26 Celsius may help to don’t dry the top leaf I hope I helped you good luck mate enjoy your grow will be nice !!

Hi there,Plants are less defensive during flowering stage and they are using all the energies for bud production.They will show heat stress( mostly if temp is above 25C or intense heat at buds,hot spot heat stress)and might show some symptoms or leaves discoloration(may be different from strain to strain.As long as I can keep my substrate pH in proper range and proper feed, I will not worry a bit about those symptoms and discoloration).All I would do is making her as comfortable as I can until harvest and focus on buds for pests, mold or rot.BTW even your RQS strain representing photo got symptoms like yours.My another sense said it’s look like Phosphorus deficiency.Happy growing... ✌️

You have signs of light/heat stress, raise the light 5 inches, and see if problems improve. Happy growing.

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?

I water with 50% distilled and 50% rain OR 50% distilled and 50% tap. I have fed once with Grow Big and it happened right after. Might have rubbed nozzle on the underside of the leaves. I water every 2-3 days and water until drop of runoff appears in tray. How much runoff?

Yellow leaves working out towards tipsYellowing 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).

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!

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!3 years ago
