Plant problems / clone question

[johnb1963]

Hello My Friends, I have two questions to ask, first one, is an ongoing issue I have been having. after 4-5 weeks of flowering, my plant start turning light green, then yellowing. I have tried everything as far as nutes, flushing. everything is good. after doing some more research on the web, it seems the problem could be light/heat stress. i'm running two cali lightworks solar extreme 250, which have an actual draw of 200 watts. my tent is 54" x 28" x 80" spider farmer, with a 6" t6 cloudline exhaust fan. with lights on, temps can reach 82. I run the light at night to help keep room cool. any thoughts?
second question. My friend gave me a clone, its a candyland, it was small, about 8" when i got her. I let her veg for 8 weeks, while doing some LST training, then flipped her to 12/12, it's been about 6 weeks, but the buds seem to have stopped growing. is that a clone thing? do clone not grow as big of buds? first 3 pics are my Gelato, with light/heat stress??? the others are the clone.

I think the deal with the Candyland clone is its phenotype - it may just be a fast finisher but with smaller yields. As for the Gelato, you are probably right about light/heat stress. You might also want to make sure no fans are pointed directly at your plants. I've had weird stuff pop up in a grow before and I realized the trouble spots were the path of an oscillating fan pointed at the top of the canopy.

johnb1963 how far is your light from the top of the canopy? I'm growing an ice cream sandwich strain that supposedly is a gelato wedding cake cross. Mine is very light sensitive. Plant turned almost completely yellow within three days. Mine was a light issue. Raised it up about 6 in and everything is great.

thanks guys, i appreciate the feedback, and the answer to your question are as followed;
1. I do fan a fan right at the top of the plants, so you can see some movement on the leaves.
2. the light manufacture recommends 12" for flowering, i raised it to 14", I will try 18" and see what happens.

one more question, since the candyland doesn't seem to be getting bigger, and based on the trichome pis, do you think I should cut her down, or wait for some amber trichomes?

Clones can be enormous. The fourth pic in the OP is Candy Land, correct? If 'yes' I'd leave it alone.

One thing to always consider: a nutrient schedule published by the manufacturer is a best estimate of their's. I find that many plants need more nitrogen than manufacturer instructions. EDIT: I mean they need more N in flower state than suggested.

thanks Peter, I use the foxfarm trio, which cuts way back on "N" the last 3 weeks of flowering.
