more problems
now my very last plant, the white window is in trouble. her leaves are mega brittle in some places. her leaves are super thick and strong like i have never seen before. she has been growing super strong and fast with really tight nodes. i cant tell what the problem is. the nut mix was really weak when i first noticed this so i mixed it stronger for the next batch, but it might have been overdone from the begining. is this overfert? what causes the ultra brittle leaves like that? that will snap by barely touching since i am leaning towards that guess, i drained 3/4 of the solution and refilled with distilled. is this ok to recover from overfert? or do i need to completely drain and run nothing but pure water?

I don't really see that as looking that bad. You need to flush it and get your ph correct. IS that the worst looking leaves? If it is those aren't that bad. I would definately clean out completely, flush a few gallons in and clean out once more and start with no nutes until it looks better. Then make sure you get your ratio's right on those nutes

they are getting worse. i really dont know what to do. i cant tell even what it is. is it nutrient burn? or defeciencies? i dont have a ppm meter. the nutrient mix is very weak right now. what should general hydro 3 part nutrient mix be mixed at? 1/2 strength? full? which stages nutrient instructions should i mix for at this size of a plant? "general mild? or vegetative? thanks so much for helping

damn, nutrient burn huh? i was just mixing the nutrients again to be stronger. the current mix is 1 gallon of water in a 2 gallon bucket at 1/4 teaspoon of each. which is 1/4 of whats reccomended per gallon for "general purpose mild"
what strength should i mix gen hydro nutrients at for a 8 inch plant? is the reccomended nutrient charts on the side what i should be mixing at? |

ok i was just reading online right now, and i have a theory. i dont think its any of the above. i am now leaning toward light burn being whats causing it. its not an obvious light burn like when a leaf lays on a cfl bulb, so it might be harder to notice. i really do have alot of light comming down on it. its a young plant and i have 7 26 watt cfls burning 4 inches from the canopy. now while as my mini-fridge is absoutely incredibly effecient in moving air and keeping literally 1 degree higher than the rest of the house at 76, that is alot of light for a small plant. there is 2 weak pc fans blowing directly over the lights and is sucked out with a 110 cfm fan keeping the ambient temps usually around 77 3 inches under the canopy, and isnt over 82 at the very top growth. BUT, can there still be too much light even though it would have to be the energy thats burning it and not the heat? take a look at the pictures again if you want and give me your advice. also i removed 2 fan leaves that were incredibly brittle, but not really brown or yellow, but a dull greyish color. can too much light cause that? what does dull greyish leaves usually indicate? thanks for taking the time to answer so many questions

anyone know whats causing the leaves so much trouble? its still happening to the leaves even though i pulled it away from the lights. i mixed the nuts using lucas method and 0-4-8 in 1 gallon of water in a 2 gal bucket. only the fan leaves it seems to be happening too.

pics to go along with last update. as i said, i remixed nutrients using lucas method. i went a little weaker since plant is still small. about 0-4-8. this was happening to the leaves at less than 1-1-1 mls per gallon.
that makes me hesitant to the idea of overfert. almost all plants i grow seem to have defeciencies because i am afraid to overdo it now. what is causing that to the leaves. i still havent got an answer and its dying. would somone please take a minute to tell me precisely what the problem is? |
