Looks like a cal/mag issue starting up or PH is imbalanced causing a lock up.

Got 3 photos. 2 in the ground 1 in 7 gallon. On all 3 the fan leaves and older leaves turning yellow at a pretty rapid rate. Prob losing 15 leaves a week rn. Purp is deeper into budding and not so bad. But should I hit them with a dose of grow big to sort it out? Or no?

Does the curl here (pic- Day 10) look like mild heat stress? Temps hover around 23-24°C (~75°F). RH ~ 65-75%. Water pH'ed to 6.5. Soil runoff tests @ 6.4-6.5. She's due for a drink tomorrow...any experts feel like throwing me a tip? Am I just overreacting?

i had this new seedling directly under a 400 watt hps at about 2-3 feet and noticed the leafs curling up. I removed it off an elevated tray thereby increasing distance and moved it to the periphery of the hps. is this a problem due to excessive heat or light or something else?

Thoughts on flushing before harvest? I’ve been reading conflicting views on whether it is necessary or even harmful. My leaves are already showing deficiencies which leads me to believe there’s not even an excess of nutrients to get rid of?

Found six different spots of small bud rot on amnesia and removed it all. Should I start flushing now and chop in the next few days? Or push it longer. Expecting rain all week so might be time to give up. Also, how much longer should she have gone?

Ok see the pic of Jen above, compare weeks one and two. She came out of the ground like this, expressing pale new growth. Began walking back the feed PH from 6.8ish to 6.0 with meh results. Possible genetic? Seen plants "grow out" of this before but she still at it. Thanks folks

Just looking for some input on how you think the grow is going so far or any advice towards growing LSD25 and Mexican Airlines. I’ve noticed some of the lower fan leaves yellowing and drying up, I read that is normal going into flowering just hope it doesn’t spread up the plant

What's up with the yellowing leaves? They seem to yellow from the outside inwards and the tips also seem burnt too. Is it nutrient burn? Excess or Deficiency? It's mostly on the bottom but its affecting some of the bigger leaves in the middle too, Watch the video for an overview!
