Potential heat stress

Adam1420started grow question 4 years ago

Is the yellowing caused by too much light and heat or is it just too much water.

It can be. If you have multiple lights that can be height-adjusted... Do a trial and error... Put one up higher... And leave one as is... Leave a seedling under the lower and see if the burn stays compared to the others under the higher light. if it's a single frame light...slant it. You'lll get your answer then. I know this isn't a straight answer but least you can deduce the possibilities with this process. If it's light the you know it's neuts! Good luck!

Also, it’s an autoflower, so you should be careful with the soil you start in, you don’t want too much nutes in there (too “hot” a soil). Autos usually need much less nutrients than reg photo period cannabis plants.

Maybe the soil is too hot? I guess you could be burning them with light if they were right up on the plant but it looks like you’re running a blurple LED and can’t imagine that is hurting it, and unless it’s scorching hot in there I wouldn’t think that’s the culprit either.

So, my other plants have surpassed this OG, unfortunately, a week younger, too. I took pictures of the PH test Do you think that was the problem? (I personal so I don't water for the first 3 weeks, lol, otherwise the above happens.)

Hello guys! Overall the plant looks light green/yellowish and pretty small, with short internodes and bottom leaves with burnt and curled up tips. I give water every 3/4 days and commonly suggested fertilzers quantities. How can I let her recover and get bigger? Thanks :)

I have a deficiency. Can you please check out my pics and give your advice? I thinks its a Magnesium deficiency, am I correct? Increase CalMag? Flush with extra water? Any tips would be helpful.

Brown spots and yellowing pictured above. My best guess is a Cal/Mag deficiency. Was feeding Botanicare Cal-Mag Plus at 1 ml/l up until ~2 weeks ago (friend has been watering while I was out of town). Before I feed her, any advice on what the problem is and how to correct it?

Is it normal for new growth 10 days into flowering to be lightening in colour? I am new and noticing that it is fairly lighter than previous veg growth before as my nutrient needs and feed has changed. Just want to be safe! Thx 😄

I don't have a PH meter, just some test strips. Can anyone recommend an inexpensive meter I can get in the UK? There's a bit of yellowing on some leaves (see my diary entry on week 8) Buds seem to be developing a bit slow Should I switch from 24 hr to 20/4 or 18/6 ?

Newer growth is lighter in color and thicker than the other leaves. She was under my humidifier so maybe drinking too much? Dry organic amendments so no additives in water. Several other grows in same feed schedule and no issues

Over the last week, I have noticed quite a lot of yellowing of leaves, along with them drying out and getting brittle. Now that I am checking the PH of the nutrients, and adjusting to 6.0, I have no idea what's going on. Any insight as to what the issue may be, is appreciated.

Yellowish color on most of the leaves and the condition did not change after watering. I suspect it's nitrogen deficiency or some pH problems. The plant is in pre-flowering, with sex being revealed. Will go into flowering soon. I watered it with 1.5l Any thoughts?

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?

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?
