First post at RIU! Veg problem. Plants "stunted"

[iamjero]

Hi everyone. Ive been growing for around 9 months now and I have a greater appreciation for all the skilled growers out there.

The issue I have, and it doesnt happen to all the plants, is some plants never really take off. They remain short and just get bushier. The leaves look fine as far as color, no spots, or brown edges, curled/deformed leaves, but no branches grow.

I maintain my pH and EC religiously according the the directions on the nutes (Ionic Grow, Bloom, and Boost)

My temperatures in the room have been pretty consistantly high in the "day" with a couple spikes over 100 (for a short period of time). Could temperatures in the low 90's be causing this?

Flowering room looks great despite the high temps, and Id say that about 50% of the plants I place in the veg room exibit this "stunted growth", and the others grow fine.

100 and 90 to hot u should be the 80 85 for good grow and 9 months u should be smoke it already

Thanks man, but I already know its too hot, and I never said I havent enjoyed the fruits of my labor.

Im asking if anyone else has experienced this, or if someone knew for sure that high temps cause the plants to dwarf during the vegatitive stage. I would buy what I needed to cool the rooms off, but I dont have much cash laying around, so Id like to get some sort of reassurance that reducing the heat will solve the issue.

here ya go assurance that is, MJ goes into shutdown mode with temps over 90 growth stops pretty much unless you add CO2 (why folks do it, speeds things up) you want your temps between 75 & 85 for sure

What should the temp be with CO2 supplementation?

look up the natural fermentation co2 method - real easy, cheap, n safe.
your plants can get stunted at 90+ deg. and wont grow, theyll attempt just to stay alive.
the co2 should help with high temps, but you should still try to bring em down to 70s, mid 80s - it will pay off in the end to do this.
