2nd grow 5th week in flower, what do u think?

just begening the 5th week of flower, i started this one from seed. thay call it bc god bud.it smells very sweet.this is only my 2nd grow.

They looks a bit heat stressed! Hows your circulation in the room?

first off what are your temps? i had a plant similar due to heat stress, still yielded decently but not anywhere near optimal

sry too double post but are you using a MH or CFL'S, definetly not a HPS

im using a mh in a small cab i have fans pushing in and pulling out, plus the light is in a cool chamber. i have my a/c set at about 78 the whole house stays kina cool, im flushing out the system and im just seeing 150ppm i think i had a little ph lock? ill reset my nuts and up date next friday.

also no matter the ventilation throw a thermometer in there for 1 day. you might be suprised

i agree heat stressed a bit

They look fine, a little bit of nutrient burn going on there, and I can't really see properly but kind of looks like a slight Potassium deficiency too (discoloured leaf margins - as in on each 'tooth' of the leaf serration), probably caused by a lockout due to either out of balance pH or some other nutrient being too high. If there's too much of a certain nutrient in the soil it inhibits the plants ability to absorb certain other nutrients, e.g - For Potassium (K) gets locked out of soil at ph levels of 4.0-5.5
Potassium is absorbed best in soil at a ph level of 6.0-9.5. (Wouldn’t recommend having a ph of over 7.0 in soil) anything out of the ranges listed will contribute to a Potassium deficiency. Potassium toxicity can cause a reduced uptake and lead to the deficiencies of Magnesium (Mg), and in some cases Calcium (Ca). It may also lead to the other nutrients to not be absorbed properly leading to other deficiencies such as: Manganese, Zinc and Iron. (it's common for a plant with nutrient burn to have nutrient lockout issues)

Don't get too concerned with it this grow, but next grow look into pH levels and such and your pot will jst keep getting better! Whoop whoop haha

Hope this helps and isn't super confusing.
Cheers.

thanks for your input. i agree i think i have some ph problems, when i leave i have 5.6 & when i return 4 1/2 days later, its at 6.5 - 6.9. my local hydro guy told me to flush w/ clearex untill i see under 250ppm tds . my first mesurement was off the scale.over1999. i flushed it one whole day untill 150ppm and then reset my nuts ( using advance nuts ) ph ballance 5.6 , kised her goodnight & closed the door. ill see if it did any good on fryday.

by the way im using rockwool , i was told that rockwool will do that ( high ph & nute lock ) i was told i should use coco?

Yea coco is sposed to be good, a bit of a hassle (but no more hassle than hydro haha) ... I tried hydro for awhile, couldn't be arsed, went back to my fine tasting, smooth organic soil herb haha.

I have been meaning to try coco but haven't had the time yet, I've heard it's sposed to be better than both hydro and soil, but that's really a matter of opinion I think. I like the taste of organic soil grown personally.

I'm on my 1st coco grow, used NFT before but didn't the system, I'm looking into getting autopots next time with coco as my medium so for the only problem I've had with it is hand watering twice a day [ lot of time and effort ] but easy to spot trouble and fix as its veery forgiving just need to gert some pics when laptop gets fixed
