Pale yellowing tips, and ill looking clones. Pics included. Help appreciated.

Hello everyone, thanks for taking the time to read yet another first timer's yell for help.

Couple of things that i feel need a professional look at.

My Plants that are currently in flowering and have been for the past 6 days have started to show pale tips to their leaves, im following instuctions on the nutes and its currently at a 6.3ph and 1.9ms, I have looked round the forums and can't find a exact solution people seem split over nute burn or a def.





The other thing thats looking bad are my clones, theyre about 11 days old now and are starting to root. The new growth on the top of the clones however is yellowing/browning and curling. I used to very very weak nutes on them at the start but have flushed them since and im wondering if this is a heat problem? I'm fairly sure the temp reached 90ish a few times. Is it worth starting over with the clones. the main plants have on been in flower 6days so its not to late i dont think.



Thanks for any help, if ive been too brief let me know and i'll hopefully be able to provide more details!

The Flowering plants are under a 250w hps + 2x 50w clf.

Clones are under 2x24w clf, and are in a humid prop box.

it looks Nitrogen deficient, did u cut the N out of their diet when you started flowering? flowering plants need alot of N in the first few weeks of flower since they really stretch and get everyhting goin, i would feed with some N right away if i were you, have u been giving it veg nutes at all since u switched over?

Thanks for the response, Since switching them over I started feeding them their new Flowering feed, which tells me on the bottle contains 5% nitro.

However the ppm in the tank falls down and the ph climbs up, i don't know if this is the plants taking in more roots than water? . i remember reading that i should only top up the water and not the nutes, ive just been making a fresh 2 liters each day and replenishing the reservoir but if i leave it a few days the ppm does drop. I shall feed them a slightly stronger solution tonight should i aim for a ppm of 1200?

I assume this is only for the large plants? Or should i be feeding the clones something too?

Anyone have any ideas what the problem is with the clones? and should i start over?

thanks duzza
